For a second-order reaction, what is the unit of the rate of the reaction?
a) s-1
b) mol L-1s-1
c) mol-1 L s-1
d) mol-2 L2 s-1
Answer : c) mol-1 L s-1
Explanation :
The general representation of unit a rate of reaction is given by (mol L-1) 1-n s-1.
where n is the order of the reaction.
For a second order reaction, n=2
The unit for rate of 2nd order reaction is,
= (mol L-1) 1-n s-1
= (mol L-1)1-2 s-1
= mol-1 L s-1.
c) mol-1 L s-1
